Transmission grinds when the clutch is engage(foot off the pedal) it grinds in neutral and all gears not in reverse, here an video clip when i push the clutch pedal in ex at the start no noise, when the pedal is released the noise starts, replaced throw out bearing, pilot bearing and pilot bearing seal. At this point i’m leaning to the transmission but before i buy a new one i just wanted a second opinion
Edit First gear is done for, has no power and grinds constantly, second gear doesn’t grind at all and drives, so yea it’s a new transmission needed

 

yep, it's something internal. u wont find a "new" one. either rebuild it or find a good used one.
